Answer:

The wind turbine generates \(19297.222\) kilowatt-hours of electricity daily.

The wind turbine makes a daily revenue of 1736.75 US dollars.

Explanation:

First, we have to determine the stored energy of wind (\(E_{wind}\)), measured in Joules, by means of definition of Kinetic Energy:

\(E_{wind} = \frac{1}{2}\cdot \dot m_{wind}\cdot \Delta t \cdot v_{wind}^{2}\) (Eq. 1)

Where:

\(\dot m_{wind}\) - Mass flow of wind, measured in kilograms per second.

\(\Delta t\) - Time in which wind acts in a day, measured in seconds.

\(v_{wind}\) - Steady wind speed, measured in meters per second.

By assuming constant mass flow and volume flows and using definitions of mass and volume flows, we expand the expression above:

\(E_{wind} = \frac{1}{2}\cdot \rho_{air}\cdot \dot V_{air} \cdot \Delta t \cdot v_{wind}^{2}\) (Eq. 1b)

Where:

\(\rho_{air}\) - Density of air, measured in kilograms per cubic meter.

\(\dot V_{air}\) - Volume flow of air through wind turbine, measured in cubic meters per second.

\(E_{wind} = \frac{1}{2}\cdot \rho_{air}\cdot A_{c}\cdot \Delta t\cdot v_{wind}^{3}\) (Eq. 2)

Where \(A_{c}\) is the area of the wind flow crossing the turbine, measured in square meters. This area is determined by the following equation:

\(A_{c} = \frac{\pi}{4}\cdot D^{2}\) (Eq. 3)

Where \(D\) is the diameter of the wind turbine blade, measured in meters.

If we know that \(\rho_{air} = 1.25\,\frac{kg}{m^{3}}\), \(D = 100\,m\), \(\Delta t = 86400\,s\) and \(v_{wind} = 8\,\frac{m}{s}\), the stored energy of the wind in a day is:

\(A_{c} = \frac{\pi}{4}\cdot (100\,m)^{2}\)

\(A_{c} \approx 7853.982\,m^{2}\)

\(E_{wind} = \frac{1}{2}\cdot \left(1.25\,\frac{kg}{m^{3}} \right) \cdot (7853.982\,m^{2})\cdot (86400\,s)\cdot \left(8\,\frac{m}{s} \right)^{3}\)

\(E_{wind} = 2.171\times 10^{11}\,J\)

Now, we proceed to determine the quantity of energy from wind being used by the wind turbine in a day (\(E_{turbine}\)), measured in joules, with the help of the definition of efficiency:

\(E_{turbine} = \eta\cdot E_{wind}\) (Eq. 4)

Where \(\eta\) is the overall efficiency of the wind turbine, dimensionless.

If we get that \(E_{wind} = 2.171\times 10^{11}\,J\) and \(\eta = 0.32\), then the energy is:

\(E_{turbine} = 0.32\cdot (2.171\times 10^{11}\,J)\)

\(E_{turbine} = 6.947\times 10^{10}\,J\)

The wind turbine generates \(6.947\times 10^{10}\) joules of electricity daily.

A kilowatt-hours equals 3.6 million joules. We calculate the equivalent amount of energy generated by wind turbine in kilowatt-hours:

\(E_{turbine} = 6.947\times 10^{10}\,J\times\frac{1\,kWh}{3.6\times 10^{6}\,J}\)

\(E_{turbine} = 19297.222\,kWh\)

The wind turbine generates \(19297.222\) kilowatt-hours of electricity daily.

Lastly, the revenue generated per day can be found by employing the following:

\(C_{rev} = c\cdot E_{turbine}\) (Eq. 5)

Where:

\(c\) - Unit price, measured in US dollars per kilowatt-hour.

\(C_{rev}\) - Revenue generated by the wind turbine in a day, measured in US dollars.

If we know that \(c = 0.09\,\frac{USD}{kWh}\) and \(E_{turbine} = 19297.222\,kWh\), then the revenue is:

\(C_{rev} = \left(0.09\,\frac{USD}{kWh} \right)\cdot (19297.222\,kWh)\)

\(C_{rev} = 1736.75\,USD\)

The wind turbine makes a daily revenue of 1736.75 US dollars.

Answer:

Explanation:

Given;

current at resonance, I = 0.2 mA

applied voltage, V = 250 mV

resonance frequency, f₀ = 100 kHz

capacitance of the circuit, C = 0.04 μF

At resonance, capacitive reactance (\(X_c\)) is equal to inductive reactance (\(X_l\)),

\(Z = \sqrt{R^2 + (X_ l - X_c)^2} \\\\But \ X_l= X_c\\\\Z = R\)

Where;

R is the resistance of the circuit, calculated as;

\(R = \frac{V}{I} \\\\R = \frac{250 \ \times \ 10^{-3}}{0.2 \ \times \ 10^{-3}} \\\\R = 1250 \ ohms\)

The inductive reactance is calculated as;

\(X_l = X_c = \frac{1}{\omega C} = \frac{1}{2\pi f_o C} = \frac{1}{2\pi (100\times 10^3)(0.04\times 10^{-6} ) } = 39.789 \ ohms\\\)

The inductance is calculated as;

\(X_l = \omega L = 2\pi f_o L\\\\L = \frac{X_l}{2\pi f_o}\\\\L = \frac{39.789}{2\pi (100 \times 10^3)} \\\\L= 6.3 \ \times \ 10^{-5} \ H\\\\L = 0.063 \times \ 10^{-3} \ H\\\\L = 0.063 \ mH\)

The use of extra pads for outriggers in crane operations is beneficial for stability and safety. However, it is important to follow safety guidelines and not stack the pads on top of each other. These pads should be placed in a single layer to spread the load evenly and improve overall stability. Placing extra pads in violation of safety guidelines is not safe.

Outriggers have an important role to play in safety and balance when it comes to crane operations, particularly in rugged terrains and areas with uneven soil, deep excavations, and heavy loads. The outrigger pads, which are made of wood, aluminum, or high-strength plastic, serve as a base for the outriggers to provide a secure foundation for the crane's support legs to work on the ground.

Hence, when the crane lifts heavy loads, the outrigger pads help to spread the load evenly across a wider surface area, reducing ground pressure and increasing stability.

Below are the true statements about extra pads for outriggers:

1. Extra pads for outriggers may be utilized to increase stability, but they must not be stacked on top of each other.

2. Extra pads for outriggers should be used to increase the surface area of support when working on rough or delicate surfaces.

3. Extra pads for outriggers may be placed in a manner that violates the correct safety guidelines.

4. Extra pads for outriggers may be utilized to boost the crane's ability to operate on a slope.

The incorrect statement among the alternatives is: Extra pads for outriggers may be placed in a manner that violates the correct safety guidelines.

When setting up an outrigger-supported crane, it is critical to follow the manufacturer's directions for proper outrigger positioning, including ground conditions, pad positioning, and leveling. The pads should be placed in a single layer to improve the crane's overall safety and stability. Also, the pads should be used in compliance with the specified load capacity, and the crane should never be operated beyond its rated capacity.

Therefore, it is not safe to place extra pads in such a manner that it violates the safety guidelines.

If you detect icing accumulation in flight, especially if the aircraft is not equipped with a deicing system, the best course of action is to leave the area of precipitation, if able, or fly to an altitude where the temperature is above freezing. This is option B.

Flying into icing conditions can be extremely dangerous as it can lead to reduced visibility, decreased lift, and a loss of control of the aircraft. Moving to a higher altitude may not necessarily solve the problem, as icing can occur at any altitude depending on the temperature and humidity conditions. Therefore, it is best to try and avoid the icing conditions altogether by leaving the area of precipitation or finding a warmer altitude. If leaving the area of precipitation or finding a warmer altitude is not possible, the pilot should activate any available anti-icing or deicing systems that may be on the aircraft. If these systems are not available, then the pilot should be prepared to make an emergency landing as soon as possible. It is important for pilots to be aware of the potential for icing and to take appropriate precautions to ensure the safety of the aircraft and its passengers. This includes monitoring weather reports and being prepared to alter the flight path or altitude if necessary.

Answer:

I think the answer is drop ceilings

Explanation:

Answer:

B

Explanation:

Answer:

a) The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

b) The change in diameter of the specimen is  - 0.015 mm

Explanation:

Given the data  in the question;

(a) The amount by which this specimen will elongate in the direction of the applied stress.

First we find the area of the cross section of the specimen

A = \(\frac{\pi }{4}\) d²

our given diameter is 20.5 mm so we substitute

A = \(\frac{\pi }{4}\) ( 20.5 mm )²

A = 330.06 mm²

Next, we find the change in length of the specimen using young's modulus formula

E = σ/∈

E = P/A × L/ΔL

ΔL = PL/AE

P is force ( 46300 N), L is length ( 201 mm ), A is area ( 330.06 mm² ) and E is  elastic modulus (60.5 GPa) = 60.5 × 10⁹ N/m² = 60500 N/mm²

so we substitute

ΔL = (46300 N × 201 mm) / ( 330.06 mm² × 60500 N/mm² )

ΔL =  0.466 mm

Therefore, The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

(b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.

Using the following relation for Poisson ratio

μ = -  Δd/d / ΔL/L

given that Poisson's ratio of the metal is 0.33

so we substitute

0.33 = -  Δd/20.5 / 0.466/201

0.33 = -  Δd201 / 20.5 × 0.466

0.33 = - Δd201  / 9.143

0.33 × 9.143 =  - Δd201

3.01719 = -Δd201

Δd = 3.01719 / - 201

Δd  = - 0.015 mm

Therefore, The change in diameter of the specimen is  - 0.015 mm

Overall BOD reduction = (BOD reduction in lagoon 1) * (BOD reduction in lagoon 2) * (BOD reduction in lagoon 3)

Now we can substitute the values and calculate the overall BOD reduction.

To calculate the total percentage of BOD reduction in the three lagoons, we need to determine the BOD reduction in each lagoon and then calculate the overall reduction.

Given:

Number of lagoons (n) = 3

Volume of each lagoon (V) = 25 m^3

Waste stream flow rate (Q) = 12.3 m^3/d

BOD degradation rate coefficient (k) = 1.2/day

The BOD reduction in each lagoon can be calculated using the formula:

BOD reduction = (1 - e^(-kV)) * 100

Applying this formula to each lagoon, we get:

BOD reduction in lagoon 1 = (1 - e^(-1.2 * 25)) * 100

BOD reduction in lagoon 2 = (1 - e^(-1.2 * 25)) * 100

BOD reduction in lagoon 3 = (1 - e^(-1.2 * 25)) * 100
